Last month, Elon Musk predicted that the electric vehicle industry will "definitely suffer" from low oil prices—a barrel of crude is about $33 today, down from more than $100 a year ago.

But don't expect that trend to last, even if oil prices stay relatively low. A new market forecast from Bloomberg New Energy Finance paints a rosy picture for the future of electric vehicles, rising from about 1 percent of global annual vehicle sales today to 35 percent by 2040—about 41 million cars.

Bloomberg has an article on BMW's refocus on EVs as well, noting the BMW iNext is a "self-driving, electric car to supplant the 7-Series sedan as its flagship model in the coming years, responding to the challenges posed by the likes of Apple and Uber Technologies" - BMW Counters Apple Threat With Self-Driving, Electric Car Push.

Tesla is still leading the way when it comes to EV sales. The NY Post reports that Tesla is rolling out a network of 105 charging stations in New York city - claiming "this means there could soon be three times as many electric-car charging stations in Manhattan as gas stations" - .
